When sourcing hospital bed lockers, prioritize ABS plastic (Acrylonitrile Butadiene Styrene) or cold-rolled steel with antimicrobial powder coating. ABS is preferred for its corrosion resistance, impact strength, and ease of cleaning, making it ideal for high-moisture environments. If choosing steel, ensure a thickness of at least 0.8mm to 1.0mm to prevent denting. The surface must be smooth and seamless to prevent the accumulation of bacteria and facilitate rapid disinfection with medical-grade cleaners.
